APA error

[mjos]

Hi Gurus,
Need help with an APA error message that came up while rebooting a rp3440 server.
The server is configured for APA.

LinkAgg0 0x001A4BF2E082 900 UP lan900 snap900 8 ETHER Yes 119

We had to reboot the server for a maintanence activity. While rebooting, the server gave the following error -
**********************Auto-Port Aggregation/9000 Networking*****************@#%

Tue May 12 EDT 2009 12:04:29.890006 DISASTER Subsys:HP_APA Loc:00000

<1006> HP Auto-Port Aggregation product found that ports in failover

group lan900 are no longer connected to each other. Port 0 did

not receive any poll packets.

It rebooted fine after some time & the APA link was also up & the server was on the network. Can somebody please help me with the reason behind this error message & the casue for this.
hp_apaportconf file has the following entries -
HP_APAPORT_INTERFACE_NAME[0]=lan0
HP_APAPORT_CONFIG_MODE[0]=LAN_MONITOR
HP_APAPORT_INTERFACE_NAME[1]=lan1
HP_APAPORT_CONFIG_MODE[1]=LAN_MONITOR

Hi,

>>>

group lan900 are no longer connected to each other. Port 0 did

not receive any poll packets.
<<<

The above message give some hints. Lan ports part of the failover group suppose to have layer 2 connectivity and able to communicate each other. From the above message, it looks lan0 and lan1 were not able to communicate for a while. Is the switch or cables disturbed for a while during that period?

[mjos]

Thanks, there was no problem from the switch or cable end. All the other servers in the same subnet were up & running.
Is it advisable to stop APA before rebooting the server.

Hi,

if you are reboot the server, you don't need to stop APA, it will be automaticaly done.

I always use shutdown -r instead of reboot.

In arp -an I dont find the IP address of the server binded to any mac address.

Hi,

so from your out seems to be only LAN0 bind to the lan900, please check the link status with lanadmin if the lan1 is up => change PPA.
